IMPROVEMENTI IN APPARATUS FOR THE MANUFACTURE OF SUGAR.

'The Schedule referred to in these Letters Patent and making nari: of the same.

To all whom Lancy concern: e v

- Be it known that I, JOHN WILLIAM HAHN, of tle clty and county of San Francisco, State of California, have invented an Improvement in the Manufacture of Sugar; and I do hereby declare the following description and accompanying drawing are sufficient to enable any-person skilled in the art or science to which' 1t most nearly appertains to make and use my 4said invention or improvements wi't-hout further inventionforexperiment.

This invention relates to that class of machines which is employed for prcssing'the sirup from sugar after it has left the centrifugal machine, for the. purpose of forming it into the loaf, and consists of certain details of construction, which will be fully described hereinafter.

In order 'to explain my invention so that others can understand its construction and operation, refer ence is had to the accompanying drawing 'forming a part of this specification, in which- A represents any square frame.` K

B is a shaft passing across this frame near its top, having secured upon it, at intervals, eccentrics C C C.

This shaft may be l'evolved by a belt in ,the usual manner or otherwise. A

A ring or band, a, encircles each of these eccentrics, and to whichvertical rods D are attached.

These rods are hinged or otherwise united by a joint to a second bar or stem, a', to the lower end of which are secured stampers or presser-s E.

The rods or stems a. pass through boxes b (l on two cross-bars, F and G, in order to insure a perfectly verticall motion of the pressers.V p

Beneath each of the pressers E areplaccd conical cups H, which sitloosely in recesses in4 the base or bed-plate, as shown, and may be removed at pleasure.

The raw sugar is first taken and passed through the usual refining process untilit has been'deprived of its sirup'and is in a crystalline form, that is when it has been removed from the centrifugal machine.

1t is then placed in the conical cups H and set in position under the pressers. The shaft Bis then'set in motion, which causes the pressers to beprcssed down upon the sugar inthe cups or molds, thus consolidating .the mass in any desired'quantity, and forming it into a loaf immediately, without waitingfor several days, as is necessary in the ordinary process.

rlhe operation of the` pressers is to gently bear down upon the sugar in the molds, and be lifted again,

without forcibly stamping upon it and the peculiar arrangement of the jointed barhand eccentrics is to accomplish this gradual pressure'without interfering in any manner with the process of crystallization.

Having thus described my invention, v

That I claim, and desire to secure by Letters Patent, isp The combination of the frame A,.shaft B, eccentric C C', rods D, stems a', boxes b d, cross-bars F and G,
